Safety goggles, in particular for work use
Abstract
Safety goggles, particularly useful as work goggles, having
temples disposed on and inclinable relative to a frame having
lenses and side guards. In accordance with the invention, a
protrusion which serves as a swivel bearing is mounted on each of
the opposite side guards, and a swivel bearing appendage having a
recess therein is adapted to be pressed onto the protrusion. The
temple is hingedly connected to the swivel bearing appendage,
whereby to permit pivotal movement of the temple relative to the
swivel bearing appendage and thus to the goggle frame. The swivel
bearing appendage is inherently elastic, permitting a portion of
the swivel bearing appendage to grip the back surface of the side
guard. A holder appendage portion of the temple may also grip the
back surface of the side guard. The temple can have its angle of
vertical inclination adjusted relative to the frame due to the
angularly adjustable engagement of the swivel bearing appendage
with the protrusion on the side guard, since the temple is moveable
with the swivel bearing appendage.

Description
FIELD OF THE INVENTION
The invention is directed to safety goggles, in particular for work
use, having temples disposed on and inclinable relative to a frame
having side guards.
BACKGROUND OF THE INVENTION
In known safety goggles of this kind, tang-like appendages are
provided at the side of the frame. The temples, in the position for
supporting the goggles, have horizontal recesses over which the
tangs fit. In order to have these recesses, the temples are widened
on the outside in this area. A structure of this kind is not
entirely satisfactory in terms of design. Furthermore, in previous
safety goggles of this kind it was difficult to mount the temples
on the frame, because either screws had to be actuated to
accomplish this, or complicated sequences of movements had to be
performed, making the assembly of the goggles labor-intensive and
therefore expensive.
SUMMARY OF THE INVENTION
With the above considerations in mind, the object of the present
invention is to provide safety goggles in which the inclinable
temples are easy to attach and to change as needed, in which the
swivel apparatus can be embodied in an aesthetically pleasing
manner and can be manipulated comfortably, and in which a reliable,
secure connection of the temples on the frame is assured.
This object is attained in safety goggles of the general type
discussed hereinbefore in that a platelike protrusion serving as a
swivel bearing is disposed on the side guard, and the associated
temple fits over or around this protrusion, preferably such that it
locks into place, with an appendage having a corresponding swivel
bearing recess. An arrangement of this kind makes a relatively flat
embodiment attainable, so that the swivel apparatus can be
integrated into the design without difficulty. Goggles of this kind
can furthermore be assembled easily and can therefore be
manufactured at a favorable cost.
In a further embodiment of the invention it is provided that a
holder appendage of the temple and/or of the swivel bearing
appendage grips the side guard from behind in a form-fitting manner
in the vicinity of the swivel bearing appendage, which is embodied
as inherently elastic. As a result of this appendage which grips
from behind, a particularly reliable, secure connection of the
temple with the frame is attained. In order to attach or remove a
temple, the swivel bearing appendage is swung back in an inherently
elastic manner in the vicinity of the swivel bearing protrusion and
thereby locks into place while returning to its initial position,
the holder appendage simultaneously gripping the side guard of the
frame from behind. In this manner not only is assembling the
goggles facilitated, but unintentionally releasing the temples from
the frame is prevented.
A hinge is preferably disposed between the swivel bearing appendage
and the temple. In a preferred embodiment, the hinge is embodied in
the holder appendage. Since the holder appendage in any event comes
to rest on inside, the hinge is thus disposed in a position which
is not only protected but is also advantageous in functional and
aesthetic terms.
In structural terms, the embodiment is preferably effected such
that a flush transition from the temple to the swivel bearing
appendage is provided on the outside.
It proves to be advantageous that abutments which limit the angle
of inclination and which engage recesses of the swivel bearing
appendage are provided on the swivel bearing protrusion. These
inclination-limiting abutments permit a free adjustment in terms of
the inclination of the temples relative to the lenses within a
predetermined angular range, yet they limit this range such that
the temples are not capable under any circumstances of assuming a
position which is unacceptable for practical use, such that they
would have to be readjusted first before being used.
It is preferably provided that fluting is disposed on the bearing
surfaces in contact with one another of the swivel bearing
protrusion and the swivel bearing appendage. As a result of these
fluted surfaces, the temples are held firmly in a desired angular
position, yet on the other hand they are easily adjusted if
required.
From the manufacturing standpoint it is particularly advantageous
that a ring carrying the limiting abutments and/or the fluting can
be mounted upon a swivel bearing plate which is fabricated integral
with the frame, in order to serve as a mounting means for the
swivel bearing appendage.
Further characteristics, advantages and details of the invention
will become apparent from the following description of a preferred
form of embodiment, referring to the drawings.
BRIEF DESCRIPTION OF THE DRAWINGS
FIG. 1 is a perspective view of the frame and temples of the safety
goggles according to the invention, seen with the temples not
attached to the frame;
FIG. 2 is a horizontal section through the area of the hinge, in
the position in which the goggles are used; and
FIG. 3 is a sectional view corresponding to FIG. 2 of the end of
the temple toward the hinge, showing the swivel appendage in the
swung-out position.
DESCRIPTION OF THE PREFERRED EMBODIMENT
The safety work goggles shown in FIG. 1 include a frame 1 with
lenses 2; the frame 1 has a side guard 3 embodied on each side. A
temple 4 is articulated or pivotally mounted on each side guard
3.
A swivel bearing plate 5 is injection molded in one piece with the
frame 1. The swivel bearing plate 5 is surrounded by a ring 6,
which has fluted surface 7 and abutments 8 for limiting the angle
of inclination of temple 4 relative to frame 1. Together, the
swivel bearing plate 5 and the ring 6 comprise a swivel bearing
protrusion 9.
Each temple 4 has a hinge 10 at one end, on which a swivel bearing
appendage 11 is disposed in articulated fashion, to permit pivotal
movement of the temple 4 relative to the swivel bearing appendage
11, as seen particularly in FIG. 3. The temple 4 is constructed so
that it has a recess 12 on its end toward the hinge. The recess 12
is formed by a step in the temple 4 and by a holder appendage 13
which adjoins the step. One of the hinge elements of hinge 10 is
defined by holder appendage 13 carried by temple 4. The swivel
bearing appendage 11 has a shank 14 parallel to its body. The shank
14 carries hinge elements defined by eyes 15 of the hinge, which
cooperate with the hinge element defined by holder appendage 13 of
temple 4. The pin of hinge 10 passes through eyes 15 and through
the hinge element defined by holder appendage 13. Because of this
construction of the bearing, it is possible to move temple 4
pivotally relative to swivel bearing appendage 11 about the axis of
hinge 10 so that the outer surface 17 of temple 4 is flush with the
outer surface 16 of swivel bearing appendage 11.
The swivel bearing appendage 11 has a swivel bearing recess 18
having a fluted surface 19 on its inside. In the assembled state,
the swivel bearing appendage 11 fits around the swivel bearing
protrusion 9, whereupon the fluting 7 engages the fluted surface 19
of swivel bearing recess 18, so that on the one hand unintentional
adjustment of the angle of inclination of the temples 4 about
swivel bearing protrusion 9 is avoided, yet on the other hand an
arbitrary angular adjustment of temple 4 relative to swivel bearing
protrusion 9 can be accomplished without difficulty at any
time.
Recesses 20 are embodied in the swivel bearing appendage 11,
permitting a swiveling movement of the temple 4 within an angular
range about the abutments 8 for limiting the angle of inclination
of temple 4. The outer rims of the recesses 20 define the angular
range of this movement.
To mount the temples 4, the front edge of the swivel bearing
appendage 11 is placed against the swivel bearing protrusion 9 and
pressed in. As a result, the swivel bearing appendage 11 is bent
back because of its inherent elasticity, and the temple 4 can be
pushed into place in the direction toward the lenses 2, whereupon
the holder appendage 13 grips the rear edge 21 of the side guard 3
from the inside. After the operation of pushing the temple onto the
protrusion 9 is complete, the swivel bearing appendage 11 locks
into place over the swivel bearing protrusion 9, causing the swivel
bearing protrusion 9 to engage the swivel bearing recess 18. All
that is required to remove a temple is to lift the swivel bearing
appendage 11 at its front edge and move it above the swivel bearing
protrusion 9, making is possible to pull off the temple toward the
back. On the other hand, it is assured that the temple cannot be
released unintentionally, because a firm seating is attained as a
result of the interaction between the holder appendage 13 gripping
the frame 1 from behind and the elastic contact of the swivel
bearing appendage 11.
In order to secure the ring 6 on the swivel bearing plate 5 such
that it cannot be twisted, it may be provided that bores be
disposed in the frame 1 to the side of the swivel bearing plate 5,
the bores being engaged by corresponding tangs of the ring 6.
